Comments: Collected from Calbiga-a creek, Lagu Lagu creek, a small creek in Guadalupe, Leyte in 1993 (Ref. 7223), Lake Naujan (Ref. 13446), Tayabas Bay (Ref. 47588), Laguna de Bay (Ref. 80824), hauled with gobies. Abundant in Lake Bombon (=Taal) (Ref. 12165, 13446). Migrated into Lake Mainit via the Tubay River, Mindanao (Ref. 4867, 13446). Museum specimens collected in 1984 from various localities, LRS-84141 (Ref. 13460). Introduced to Lake Lanao (as Hypseleotris agilis) (Ref. 10888, 13446) and may have caused the extinction of 17 endemic cyprinids through the heavy predation by the species which was inadvertently stocked in the lake with Nile tilapia fingerlings coming from a government hatchery in Surigao del Norte (Ref. 48328). Abundant in Lake Lanao based on 2001 report (Ref. 70969). Also Ref. 5259, 95183.

Short description

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 9. Body relatively large, stout and cylindrical with a dorsally flattened head; generally greenish brown with 8-10 dark bars across sides and large black blotch at base of pectoral fins; lower half of head tan or yellowish with 3-4 dark brown to reddish stripes radiating from lower part of eye (Ref. 44894).

Adults occur in fresh water, estuaries and inshore (Ref. 86252). Found in a variety of habitats including rivers, swamps, coastal streams and floodplains over mud bottoms, often among dense aquatic vegetation or the cover of undercut banks. They feed mainly on aquatic insects and nymphs, but also takes lesser amount of algae, other aquatic plants and small crustaceans. Pelagic larval stage is found in marine water, but adults are always found in freshwater (Ref. 44894).

IUCN Red List Status (Ref. 115185)
